Question

The human body consists mainly of three elements. About 1/10 of a body's weight is hydrogen, 16/25 is oxygen, and 1/5 is carbon. What is the weight of the hydrogen, oxygen, and carbon in the body of a person who weighs 134 lb?

Answer 1

Hydrogen = 13.4

Oxygen = 85.76

Carbon = 26.8

Explanation:

H= 13.4

When you multiply by 1/10 all you have to do is move the decimal point to the LEFT.

So... 134←. = 13.4

O= 85.76

134×
`(16)/(25)`=85.76

C= 26.8

134×
`(1)/(5)`=26.8
